    Recent strong s.w. winds have created windslabs up to a metre thick on lee slopes in the alpine (primarily N- E aspects). Although these slabs are starting to settle out with warm temps it is still possible for a skier to trigger these slabs.

    In many areas east of the divide where the snow is shallower the midpack overrides a layer of weak basal facets. Be extra cautious of thin snowpack areas where the chance of triggering this layer is highest.
